| 摘 要： | 储集层岩石的孔隙结构非均质性对于油气的渗流规律以及水驱油效率都具有重要的影响。利用分形理论对孔隙结构的非均质性进行研究。结果表明,分形维数不同孔隙结构不同,所研究的储集层具有单一分形（分形维数2.690 7～2.814 0）和分段分形特征（分形维数2.414 8～2.995 2）;以分形维数为基础,可以根据孔喉渗透率贡献判断孔隙结构的非均质性和复杂程度。 |
| 关 键 词： | 孔隙结构 分形维数 区间渗透率贡献值 |

| Abstract: | The pore structure of reservoir rocks has important effect to oil-gas seepage and waterflood efficiency.The fractal dimension can describe quantitatively the complexity and the heterogeneity of pore structure.The results show that the reservoirs are of singular（fractal dimension 2.690 7～2.814 0）and multiple fractal（fractal dimension 2.414 8～2.995 2） natures using fractal geometric formula with two parameters.By fractal dimension as the foundation,the complexity and the heterogeneity of pore structure can quantitatively be judged according to the permeability of contribution of pore throat. |
| Keywords: | Pore structure Fractal dimension Interval permeability contribution |
